This exceptional "Indigo Crest" tanzanite in a rectangular cushion mixed cut boasts an impressive weight of 16.87 carats. Its intense "Deep Violetish Blue" color quality displays an exceptionally deep royal blue color play with vibrant violet nuances and high optical depth.

Thanks to its harmonious proportions, strong saturation, and excellent transparency, the gemstone unfolds an intense luminosity and striking presence. The elaborately faceted cushion cut ensures powerful light reflections across the entire surface of the stone.

The IGI-certified specimen features a natural inclusion pattern and, due to its combination of size, color quality, and radiance, is one of the most coveted tanzanites in the premium segment. High-quality tanzanites of this magnitude are extremely rare and sought after by collectors, investors, and luxury jewelers alike.

Note:
Our tanzanites are carefully selected based on color intensity, clarity, cut quality, and overall impact. Many tanzanites offered internationally may appear high-quality in photos but often do not match the depicted colors in reality or exhibit visible surface features and quality deviations.

Every tanzanite we offer is inspected before sale and comes with an original certificate. Additionally, you benefit from a right of return and a secure purchase from a German provider with declared VAT.

Tanzanites are among the rarest gemstones in the world, found exclusively in a small region at the foot of Mount Kilimanjaro in Tanzania. Globally, there is only one known mining area for tanzanite. The known deposits are considered highly limited, making high-quality specimens increasingly rare and internationally coveted.
